Stressing

Mc

So this is my first post, but my partner are working on baby#2. I'm about 2 weeks late and have had morning sickness changes in CM and sore breasts. I've had 2 neg PT with a week of each other. I'm so distraught about this but I'm still showing no signs of AF. So what should I do I needed up making an appt with my obgyn. Just to be sure. But has anyone else taken several PT and had neg results buy still ended up being pregnant?
